The 3 main problems I found

These shingles have lost between 45% and 70% of the granules. This is always the first sign that your roof is past its prime and may need replacing.

Through the roof, I could spot where the staples were popping through the shingles or pushing the shingles up. This can cause leaks by having open penetrations in your roof. In this picture, the arrows all point to shingles popping up due to staple pops.

There was a hand full of shingles that the wind had blown and flipped backward. This causes the tab on the shingles to either complete break, crack, or crease causing the fiberglass to break in the shingle.
